Comparing performance of: Inline Function vs Hooks vs Without useMemo vs With useMemo vs Child without memo vs Child with memo (React 18)
Test on isEqual performance
Compare the performance of five ways to traverse an array and accumulate a computed numeric result. All test cases execute the same work on the same input data. Note that for...in enumerates property keys rather than using the array iterator, so its semantics differ from for, for...of, forEach, and reduce.
